<P><STRONG>Function</STRONG>
<P>
Deletes a named component from a Field.
<P><STRONG>Syntax</STRONG>
<BR>
<TT><STRONG><BR>
&#35;include &lt;dx/dx.h&gt;<BR>
<P><BR>
Field DXDeleteComponent(Field f, char *component)<BR>
</STRONG></TT><BR>
<P><STRONG>Functional Details</STRONG>
<P>
Deletes <TT><STRONG>component</STRONG></TT> from a Field
<TT><STRONG>f</STRONG></TT>.
Any
attributes associated with the named component are also deleted
from the Field.
<P>
Deleting a component from a Field may alter the structure of the
Field in significant ways. For example, if the "positions"
component is removed,
any other components that contain references to positions
become invalid.  For this reason,
<TT><STRONG>
DXChangedComponentStructure
</STRONG></TT>
may be used to ensure that the remaining structure of the Field is
consistent.
<P><STRONG>Return Value</STRONG>
<P>
Returns <TT><STRONG>f</STRONG></TT> or returns <TT><STRONG>NULL</STRONG></TT>
but does not set an error code if the component
does not exist.
